How can I fix Access denied error code 16?

Use a VPN

  1. Purchase a VPN subscription plan (we recommend PIA)
  2. Download the VPN client to your PC
  3. Install the VPN client and launch it
  4. Log in to your VPN account
  5. Connect to a server of your choice
  6. Check if you still receive the error

Using a VPN is the most common fix you can apply if you notice that certain websites aren’t available to you.

Whether your ISP restricts your access to the websites, or you may be in a region where the site is not available, a VPN such as PIA can take care of it.

Additionally, a VPN will also encrypt your traffic and re-route it, shielding it from potential attackers, hackers, spies, and even your ISP.

Check your security software

maximize VPN security

Sometimes security software on your computer, including but not limited to your firewall or antivirus, may limit your access to various resources.

If, say, your firewall was to blacklist certain websites on your computer, you would be unable to access them without removing the firewall rules.

Therefore, it’s not impossible that you’re receiving Error Code 16 because of an overzealous firewall or antivirus piece of software.

Fortunately, that’s quite easy to fix. You just have to look into your security software’s configuration and make sure it doesn’t limit your Internet access.

Use another device

Sometimes, your device may not be properly configured to access certain websites, in which case it will become restricted.

To rule out anything wrong with the device you’re receiving the Access denied Error Code 16 on, just try using another device.

However, make sure you stay within the same network as the original device.

If you can access the websites normally on the second device, at least you’ll know there’s something wrong with the original one.

You can also try using another network, to rule out any network-based limitations.

Update your Windows

Microsoft releases updates for its popular OS (Windows) on a regular basis, and making sure they’re always installed is actually great.

There’s a good reason why these updates get released so often, so you might as well apply them.

  1. Open the Settings app (Windows Key + I)
  2. Navigate to the Update & Security section
  3. Click the Check for updates button

Not only is an up-to-date Windows machine more secure against all kinds of threats, it’s also less prone to issues such as the Access denied error code 16 one.

Expert Tip: Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken. We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.

Therefore, make sure you’ve applied the latest batch of updates, restart your PC, and check if the error is still there.

Use a different web browser

Sometimes Access denied error code 16 can be related to your browser and its configuration.

To check if your browser is the problem, we advise accessing the website using a different browser.

Microsoft Edge could be a good choice, but if the problem is related to your system, it’s rather likely that the issue will manifest itself in Edge as well.

Therefore, it might be better to use a third-party browser such as Firefox or Opera in order to troubleshoot this issue.

If you don’t encounter the issue while using a different browser, it’s rather likely that your default browser’s configuration is what’s causing it.

So you might want to either adjust your settings, reset your browser, or replace it altogether.

Check your system date and time

Many services perform date and time checks on your system before giving you the green light to access them.

So it wouldn’t be the craziest thing if you wouldn’t be able to access a specific website because your date and time are not set correctly.

We know this may sound a bit far-stretched, but trust us, it’s happened to other users.

Therefore, we recommend you to check if your date and time are set correctly.

If not, you can easily take care of this issue by setting the time and timezone to Auto.

As long as you’re connected to the Internet, your date and time should never be wrong again.

Contact your ISP

This is perhaps the most overlooked suggestion ever.

If contacting the ISP could be avoided, many would gladly follow any other suggestion, no matter how absurd.

However, this is in fact one of the most effective way to solve any connectivity issue that’s not related to your PC (or any PC component).

It’s a known fact that ISPs can block various websites, and this may be exactly why you’re getting that annoying Error Code 16 in the first place.

Call them and ask if they’re actively blocking the website that prompts you with that error. If they do, you can rule out any PC-related problems.

Don’t be disappointed, there are still ways to get around this limitation. Using a VPN, for instance, can easily circumvent ISP website blocks.


All things considered, the Access denied error code 16 issue can prevent you from accessing some of your favorite websites, but there are ways to fix it.

If you encounter this problem, make sure to try our solutions and remember that simply using a VPN can fix the problem in most cases.
